Abstract

The invention provides an ultrahigh fill corrugated steel arch structure and a construction method, and belongs to the technical field of bridge and culvert construction. The method comprises the following steps: B, mounting an outer-layer arch structure, and mounting a displacement sensor and a strain sensor to monitor and feedback displacement data and strain data of a corresponding part of theouter-layer arch structure; c, mounting an inner layer arch structure; f, performing first-stage filling until the displacement data and the strain data reach a preset limit value standard; i, pouringconcrete between the outer-layer arch structure and the inner-layer arch structure, and waiting until the concrete reaches preset strength; and J, carrying out second-stage filling until a preset standard is reached. The structure comprises the outer-layer arch structure, the inner-layer arch structure, a filling body structure, the displacement sensor, the strain sensor and a data transmission module. High stability and safety can be achieved in the whole process of installation construction and actual use in ultrahigh fill engineering.

Description

technical field [0001] The invention belongs to the technical field of bridge and culvert construction, and more specifically relates to a construction method for an ultra-high fill corrugated steel arch structure. Background technique [0002] The soil-covered steel corrugated plate arch bridge is a new bridge and culvert structure with strong deformation adaptability. It can interact with the surrounding compacted soil to generate soil and structure, and mobilize the soil to jointly bear the external load. Compared with the traditional concrete arch ring, the steel corrugated plate structure has light weight, simple construction, short construction period, low cost, little disturbance to the foundation, and low requirements for the foundation, so it has broad application prospects. When the span of the steel corrugated plate arch bridge is small or the covering soil is not high, the structure can rely on its own stiffness to meet the design and use requirements of the brid...
